Onboard satellite communication systems generate and manage coverage beams over the
Earth. Depending on data traffic requirements, the number of beams, side lobe levels, nulls …

The antenna is one of the key components of satellite communication load. To address the
evolving requirements of future satellite communication systems, the sparse planar array …

The design of isophoric phased arrays composed of two-sized square-shaped tiles that fully
cover rectangular apertures is dealt with. The number and the positions of the tiles within the …

The aim of this paper is to discuss a novel technique for sparse array synthesis. The
synthesis strategy is based on a sparse-forcing algorithm using an improvement of the …

The modular design of planar phased array antennas with hexagonal apertures is
addressed by means of innovative diamond-shaped tiling techniques. Both tiling …

This article presents a differential evolution algorithm with a new encoding mechanism and
Cauchy mutation (DE-NEM-CM) for optimizing large unequally spaced planar array layouts …

We present a deterministic iterative method for synthesizing equal-amplitude aperiodic array
radiating patterns with arbitrary upper bounds and are capable of scanning in a wide …

This contribution describes the design of a multibeam parabolic reflectarray to produce two
adjacent beams per feed in orthogonal circular polarization (CP) simultaneously at the …

We introduce an effective antenna array synthesis algorithm which is aimed to the
generation of sparse arrays radiating patterns with arbitrary upper bounds. The approach …

Thinning antenna arrays through quantum Fourier transform (QFT) is proposed. Given the
lattice of the candidate locations for the array elements, the problem of selecting which …
